T 0 all whom it may concern:

Be it known that I, J osnrrr GoULDBoURN, a subject of the King ofEngland, residing at Leicester, in the countv of Leicester, Eng land,have invented certain Improvements in Machines for Inserting Nails inI-Ieels, of which the following description, in connection with theaccompanying drawings, is a specification, like reference characters onthe drawings indicating like parts in the several figures.

This invention relates to machines for insert-ing nails in heels, andwhile many features of the invention may be used advantageously in othertypes of machines, the in vention is herein shown and described asembodied in a machine for attaching heels to boots or shoes.

An object of the present invention is to improve the construction ofmachines of this class so that they may be operated at a higher rate ofspeed than has before been possible.

A further object of the invention is the improvement of such machines sothat they may be more readily adjusted to operate upon different classesor sizes of work than has been possible with machines as heretoforeconstructed.

I have shown the invention herein embodied in a machine for attachingheels to shoes by nails driven from the inside of the shoe. It will beunderstood, however, that features of the invention are capable of useas well in connection with machines for driving heel-attaching nailsfrom without a shoe.

A novel feature of the present invention consists in the provision in aheel-attaching machine of a die-block provided with driver passages; amovable nailtransferrcr arranged to be reciprocated to supply successivesets of nails to the die-block for attaching successive heels, and aplurality of movable heel-holders arranged to be brought successivelyinto attaching position by the successive reciprocations of thenail-transferrer- Another feature of the invention consists in novelmeans for presenting heel-blanks for the operation of the machine. Inthe preferred embodiment of the invention this means comprises arotatable carrier for heel holders having radially disposed armsextending outwardly from a central hub, the arms being spacedsubstantially 120 apart and carrying on their outer ends the heelholders which are moved from receiving position to anintermediateposition and then to nailing position by an intermittentrotation of the carrier.

In this connection the invention contemplates also a novel mechanism foreffecting the required rotation of the carrier. It has been foundadvantageous to divide each rotation of 120 into two movements. To thisend cooperating cams may be arranged to rotate said carrier after thenailing. operation for any desired portion of 120, then to maintain thecarrier stationary and finally to rotate the carrier for the remainingportion of the 120 necessary to move a holder into nailing position.

Another feature of the invention consists in the provision of apressure-plate for engaging a heel, means for adjustably sustaining saidplate in a position inclined longitudinally of the shoe and aheel-holder for sustaining a heel in line with the heel seat of the shoearranged for adjustment simultaneously with said pressure-plate. In theconstruction shown, the heel-holder is carried by the pressure-plate sothat the relation of the holder to the face of the pressure-plate is notchanged by adjustment of said pressureplate. The pressure-plate isengaged by the tread face of the heel and is adjustable about an axisthat is at or near the level of the heel seat of a shoe. Such adjustmentpermits driving the attaching nails at the desired inclination to thetread face of the heel.

The heels are held upon the heel-holders by gages arranged to engage thebreast and rear of the heel and these gages are arranged for adjustmentto accommodate heels of different sizes. To facilitate the adjustment ofthe several sets of gages the present inven tion also contemplates theemployment of means providing connection between said sets of gages,whereby they may be adjusted simultaneously. As Will be obvious, the arrangement may be such that the position of all the breast gages, or allthe rear gages, or

all breast gages and rear gages may be simultaneously adj usted. Inorder that the centers of heels of'different sizes may occupy the sameposition on the heel-holder, the construction herein illustrated is suchthat the breast and rear gages may be simultaneously adjusted inopposite direct-ions upon the respective holders.

In the machine herein disclosed the dieblock will not always lie atprecisely the same elevation in its nail-receiving position. To avoidthe necessity of vertically adjusting the nail-transferrer for everyalteration in theposition of. the die-block the, present inventionincludes a provision of means whereby the transferrer is mechanicallymoved vertically into close relationto the facev ofthe die-block in its.movement into nail-delivering position, and is restored to its initialposition. when returned tonailreceiving position, The construction shownis such that the transferrer is. brought yieldingly into contact-withthe face of: the dieblock so. that variations in position of; thelatter, are mechanically provided for. This construction as will be,apparent is. particularly advantageous. when the face of the die-blockhas a somewhat convex configuration, the. face of the transferrer, beingmade concaveto fitthe die-block. In the embodiment of; the: inventionselected for purposes of illustration the die-block is arranged to entera shoe and tosupport the shoe. upon it. The die-block is arranged formovement intoandout ofattaching position to facilitate arranginga shoein position upon it. The nails are supplied to the die-block while. thelatter is in its inoperative position. To insure that the die-block willbe in the precise position required to cause the nail passages of thetransferrer to be in line with the nail cavities of the dieblock thepresent invention includes an arrangement whereby the nail-transferrerin its movement into nail-delivering position mechanically adjusts thedie-block into proper position.

Other. features of the inventionv will be hereinafter describedzanddefined in the claims.

In the drawings whichillustrate one embodiment-ofthe, invention, Figure1 shows a side elevation of the upper portion of a heelattaching machineembodying the invention; Fig. 2'is aview infront elevation of the parts.show-ninFig- 1; Fig. 3 is aview in horizontal section of'the machine;Fig. 4

is a view, similartoFig. 3, illustrating a:

The drawings illustrate the present invention applied to a machine ofthe type shown in Letters Patent of Great Britain No. 5084 of 1903 toBates at al. As will be evident from the nature of the invention, it isalso applicable to other types of heel-attaching or heel-loadingmachines.

The machine shown in the present drawings includes, as in the priorpatent above mentioned, a work-support 1 upon which Ithe boot or shoe tobe heeled is placed and an oppositely disposed pressing member 32. ,Theupper end of the worksupport is provided. with a die-block 2 havingdriver passages, and drivers carried by a driver bar 13 are arranged inthese passages and are automatically actuated to drive nails through thesole of a shoe into a heel in the manner described in said patent. Thework-support is arranged to slide in a horizontal 'guideway 4 carried bya vertically reciprocating member 6. The work-support is moved by theoperator from the position indicated by dotted lines in Fig. 1' intothat shown in full lines in said figure to place a shoe in attachingposition.

According to the present invention a nailtransferrer 8 is employed tosupply nails to the die-block 2 and as shown 18 arranged to convey nailsfrom a nail-assorting and delivering mechanism 10 of any suitableconstruction to said die-block. The transferrer 8 is splined upon avertical spindle 12 rotatably mounted in bearings lt upon the frame,said spindle having a handle 16 by means of which the transferrer may bereciprocated by the operator. In the movement of the transferrer S intonail-receiving position it is raised by means of a spiral cam surface 18on the block 20 mounted upon the frame cooperating with a runner 22-uponthe transferrer arranged to engage said cam surface. A spring 24; (seeFig. 2) tends to keep the runner 22 in engagement with the cam surface18. The block 20 is preferably adjustably secured to the machine frameso that the position of the cam surface 18 may be varied to raise orvlower the path of movement of the transferrer. A convenient;construct-ion comprises .a nut 26 screwed upon the spindle 1 andengaging the lower face of the hub of the handle 16, said handle beingsplined upon the spindle l2, and the upper face of said hub engaging theblock 20. The block 20 is secured to the machine frame by a rib andgroove connection or any convenient construction permitting it to beadjusted in a vertical direction by the nut 26 and preventing itsrotation.

A heel carrier 28 is provided with a stud 3O rotatably mounted inabearing 31 formed upon a slide 32 (see Figs. 3, 4 and 8). The slide 32is sustained upon a foot 34, said foot being formed upon a curved slide36 hereinafter referred to. The slide 32 is coupled to the transferrer 8so as to move therewith. The construction shown includes a link 38attached at one end by a universal joint 40 to the slide 32 and at theother end by a universal joint 42 to one arm of an elbow lever 44, saidelbow lever being pivoted on an arm 46 (see Fig. 2) secured to a post 48hereinafter referred to. A frame 50 is secured to the upper end of thespindle 12, said frame sustaining a vertical rod 52. A link 54 arrangedto move freely upon the rod 52 is pivotally connected with the other armof the elbow lever 44. As will be obvious the connections between thetransferrer and the slide 32 permit the slide 32 to be adjustedvertically or swung about a horizontal axis if desired.

The heel carrier 28 is provided with a three-armed lever 56 (see Fig. 4)rigidly secured to the stud 30. Each arm of the lever is provided with aroller 57 at its end which, as the slide 32 is moved to and fro by thetransferrer 8, is engaged in turn by two cam surfaces, one 58 formed ona plate (30 (see Fig. secured to the curved slide 36, and the other 62being formed on a plate or member 64 pivoted to the curved slide. 011the movement of the nail-transferrer into nail-delivering position, theroller upon one of the arms of lever 56 is engaged by the cam surface 62and the carrier 28 is partially rotated to bring the roller into theposition shown in Fig. 3. In the construction illustrated, this partialrotation amounts to about 75. In the move ment of the nail-transferrerinto nail-receiving position the cam surface 58 is engaged by the rollershown in Fig. 3 and rotates the carrier 28 substantially 45 farther tobring a heel-holder thereon into alinement with the post 48. The plateor member 64 carrying the cam surface (52 engages a stop 66 on thecurved slide 36 and is held from movement in the reverse direction by aspring, not shown, which permits a roller to pass by said plate 64 inthe movement of the nail-transferrer into receiving position. The camsurface 58 terminates at its forward end in a recess arranged to receiveone of therollers 57 on the move ment of the corresponding holder intooperative relation with the driving mechanism, thus locking the carrieragainst angular movement until the slide 32 is moved rearwardly afterthe operation of the drivers.

Each heel-holder as illustrated comprises a back gage 68 having aV-shaped recess to receive the curved end of a heel and arranged toslide in guideways upon the carrier 28, and a breast gage formed as astraight bar 70 for engaging the breast of the heel. Each breast gage iscarried by a plate 72 arranged to slide in guideways toward and from theback gage and is yieldingly held toward the back by a spring 74. Theplates 72 bear against the tread surfaces of the heel blanks and serveto position them properly for presentation to the upper pressing member32. To permit all the back gages 68 to be adjusted simultaneously, rackbars 76 are formed upon them and are arranged to mesh with a pinion 78rotatably mounted on the stud 30. Integrally with the pinion '78 isformed a beveled gear 80 (see Fig. 5) meshing with a second beveled gear82 mounted on the shaft 84 journaled in the slide 32 and arranged to beactuated by the operator. During the rotation of the carrier 28 in theoperation of the machine, the shaft 84 will be turned idly by the gear80 which rotates with the carrier, there being sufficient frictionalresistance to movement of the back gages on their support toprevent themfrom being moved relatively thereto in the rotation of the carrier 28.Each breast gage 70 when no heel is in the corresponding heel-holder isheld by its spring 74 in engagement with a wedge-shaped block 85, aprojection 83 upon said breast gage coming in contact with said block.The wedge-shaped block 85 is carried by the adjacent back gage 68 sothat as the back gages are adjusted by the operator toward or from thecenter of the carrier 28, the breast gages are adjusted in the reversedirection. As will be obvious this construction permits heels ofdifferent sizes to be conveniently inserted in the holders and to beretained upon the holders with their centers in substantially the sameposition.

The post 48 is mounted for vertical adjustment in the head of themachine and is held from rotary motion therein,a hand wheel 86 beingprovided to facilitate its adjustment. The curved slide 36 is mounted inguideways 88 formed upon the lower end of the post 48 and said slide isprovided with means for adjusting it in said guideway,'a convenientconstruction including a worm 90 carried by a spindle 92 journaled inthe post 48, said worm engaging worm teeth formed upon the curved slide36. By adjusting the slide 36 in its guideway the carrier 28 may besustained in an inclined position so that a heel against which the heelseat of a shoe is pressed may be held in an. inclined position and thenails consequently driven in an oblique relation to the lifts of theheel. As shown in Figs. 1, 5, and 8, the machine is adjusted forinserting nails at an inclination to the tread face of the heel. Theguideway 88 is preferably curved in the arc of a circle, having a centerat or near the level of the heel seat (see ment.

Fig. 8) so that the pressure-plate formed by the slide 36 cooperatingwith the breast gages with which the tread face of the heel come incontact is adjustable about an axis that is approximately at the levelof the heel seat. The post 48 is slotted at 94 (see Fig. 4) and aclamping bolt 96 actuated by a handle 97 is provided to cooperate withsaid slotted post to hold the curved slide 36 in adjusted position.

The nails are delivered to the die-block 2 with said die-block in itsouter position shown in Fig. 3. To insure that the the block shall be inproper position for the recept-ion of the nails, the machine shown ineludes means for adjusting it into correct position in the movement ofthe nail-transferrer into nail-delivering position. This is shown as alever comprising arms 98 and 99, said lever being pivoted upon the frameat 100 and actuated by the transferrer 8 by means of alink 102 connectedto arm 99 and an eccentric 104-, for actuating said link said eccentricbeing secured to the spindle 12. A lug 106 is formed on the work-supportfor engagement with the arm 98 so that when the tranSferrerS is movedinto nail-delivering position, as shown in Fig. 3, said arm 98 will movethe die-block outwardly in case itis not in its outermost position, asuitable stop device, not herein shown, being provided if desired tolimit outward movement of the die-block.

In the operation of the machine above described, the work support beingin its outer position, the nail-transferrer carrying a gang of nails ismoved by the operators attendant into nail delivering position above thedie-block. In its movement it adjusts mechanically the die-block intoproper position to cause its nail cavities to be in line with the nailpassages of the trans ferrer when the latter is in position above thedie-block, and also moves a heel-holder in which a heel has beenpreviously inserted by the attendant part way toward attaching position.The nail-transferrer is brought into close relation to the face of thedie block by the spring 24:, which yieldingly depresses said transferrerin its move- The transferrer after delivering its nails to the die-blockis returned by the attendant to receiving position. In its returnmovement it is raised by the cam 18, so that in receiving position it isin close relation to the nail-supplying mechanism. Also in its returnmovement, it completes the movement of aheel-holder into attachingposition. A shoe may then be placed upon the work-support by theoperator, the

work-support moved into attaching position and the machine started whichthereupon automatically lifts the jack to place the work under pressure,as in the machine of the prior patent above mentioned, and

' drives the nails from within the shoe into the heel. After theoperation of the drivers the jack descends and the heel which has beenattached to the shoe is drawn downwardly out of its holder. While a shoeis being heeled, the attendant may insert a heel for the next shoe inthe holder next to that in attaching position. It will be evident that agreater or less number of heelholders than three may be employed. lVherethree are used the holders may be conveniently reached from the side ofthe machine, as will be apparent from Fig. 4.

hen a change is made in the size of the heels being attached adjustmentof the gages is desirable. It will be seen that in properly adjustingthe gages upon one holder to fit a heel, the gages upon the remainingholders are simultaneously adjusted to the same extent, and separateadjustment of the gages upon the different holders is thereby renderedunnecessary. In case adjustment in inclination of the pres sure-plate isdesired, it may be secured by adjusting the curved slide 86 in itsguideway, since the carrier 28 for the heel-holders is'supported by theslide 36. It will be seen that in adjusting the latter, adjustment ofthe former to the same degree of inclination is secured. The adjustmentof the slide 30 is about an axis located at or near the heel seat of theshoe as shown in Fig. 8, and it will be noted that this feature isadvantageous in that the heel may be adjusted in inclination withoutdisplacing its heel seat face longitudinally of the shoe.

As will be apparent from the above description, modifications in themachine herein disclosed. could be made without departing from thepresent invention. For example, the machine shown could be adapted, ifdesired, to secure successively to a shoe a heel blank and a top lift.It may also be observed that the term nails herein employed is intendedto include slugs or other equivalent devices.

A machine of the class described, having, in combination, relativelymovable work-engaging members, driving mechanism associated therewith, arotatable carrier having three radially disposed heel blank holders,said carrier being constructed and arranged to present successive blanksto the work-engaging members by intermittent rotation in one directionand to receive a blank when one of the holders is in a positionsubstantially 2&0" from the driving mechanism, means for rotating saidcarrier to move successive holders from receiving position to drivingposition, and means for engaging the tread surfaces of the heel blanksto position them in a common plane, each blank holder being constructedand arranged. to engage trictionally the edges of a blank therebypermitting its removal from the holder by a movement at right angles toits tread face after the operation of the driving mechanism and beforefurther rotation of the carrier.

29. In a machine of the class described, the combination with a nailblock, of a nail transterrer mounted for movement to and from said nailblock, driving mechanism and a rotatable blank carrier, said carrierbeing rotated in one direction fol-presenting successive blanks to saiddriving mechanism by the movement of said nail transterrer in oppositedirections.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
